Distribution and Determinants of Volleyball Related Injuries

Kerry MacDonald BKin, MEd, PhD Candidate Level III NCCP

• PhD Candidate in Sport Medicine
• Sport injury epidemiology - Study of

the distribution and determinants of disease/illness within a given population

• Sports related injuries are predictable and
• ften preventable
• The following is a summation of the

current literature.

• Primary
• Prevent the injury from ever occurring
• Secondary
• Early detection, prevention of

progression of overuse injuries

• Tertiary
• Rehabilitation

• Intrinsic
• Specific to the athlete
• Can be modifiable (Fitness, strength,

flexibility, technique)

• Or non-modifiable (previous injury,

age, gender)

• Extrinsic
• Not specific to the athlete, external

factors

• Can be modifiable (Training Hours,

Jump Count)

• Or non-modifiable (court surface, ball

weight)

Meeuwisse, 2007

• Acute Injuries
• Injuries with a specific

defining moment of injury.

• Fingers and ankles are

most common regardless of gender

• Concussion rates are

unknown

• Overuse Injuries
• Injuries that lack an insidious onset.
• Most common: Knees, Back, Shoulders
• Early symptoms often go unreported as

athlete attempt their own self management techniques

• Establishment of an open and honest

dialogue allows for early detection

• 4.6 injuries /

• 1 injury every

31 games or practices

• 2.7/1000hrs

in AB

• The most common predictor of future injury is

previous injury

• Have a detailed understanding of player’s

injury history

• Assure full recovery before full return to sport
• Err on the side of caution
• Secondary injury is often more severe than

primary injury

• Type: Acute
• Risk Factors: Blocking
• Preventative Measures
• Equipment: Tape (no

evidence)

• Coaching:
• Teach proper hand

position for blocking

• Caution when attacking
• ff of boxes

• Type: Acute
• Risk Factors:
• Intrinsic: Balance
• Extrinsic: Attacking and Blocking
• Preventative Measures
• Equipment: Ankle Braces
• Intervention: Balance board training
• Coaching:
• Reduce tight attack/block interactions
• Auto re-serve OR wider centre line

• Risk Factors:
• Intrinsic: Balance, Female, Landing

Technique

• Extrinsic: Attacking and Blocking
• Preventative Measures
• Equipment: Knee brace (no evidence)
• Coaching:
• Teach proper landing technique
• Reduce tight attack/block interactions
• Auto re-serve OR wider centre line

• Landing Technique

• Landing Technique

• Type: Overuse
• Risk Factors:
• Intrinsic: Jumping ability, ankle ROM,

landing technique

• Extrinsic: Attacking/Blocking, Jump load,

position (OH and Mids)

• Preventative Measures
• Equipment: Patellar straps/taping

• Coaching
• Gradual increases in jump load
• Teach “soft” landing technique

• Type: Overuse
• Risk Factors: Attacking, Jump

Load?

• Preventative Measures
• Coaching:
• Teach arm swing

technique with trunk rotation

• Type: Overuse
• Risk Factors: Repetitions, Glenohumeral

rotational strength difference, Asymmetric pectoral flexibility.

• Preventative Measures
• Equipment: Thera band
• Coaching:
• Gradual increases in swing load
• Low elbow arm draw?

• Low elbow

arm draw?

• Type: Acute
• Risk Factors: warm-up?
• Preventative Measures
• Coaching:
• Drill and warm-up design to reduce

placing athletes in vulnerable positions

• 3.1 injuries per 1000 competition hours

(FIVB)

• Indoor ~4.6 per
• Similar rate of overuse injuries
• Back
• Knee
• Shoulder
• Lower rate of acute injuries

• Most Injuries occur during blocking and

attacking (acute and overuse)

• Be considerate of load change
• Reduce risky tight net interactions
• The best predictor of future injury is past

injury

• Know your players injury history
• Slow return to play
• Playing through pain is not necessary

• Landing technique
• Knee over toes
• “Soft”
• Reduce injury, improve responsiveness
• Two feet
• Arm swing
• Trunk rotation – “Torque”
• Reduce back arch
• Low elbow draw?
